T1 EP.1 – The Choice of Weapons
9 de julho de 200452 minStrategy refers to the implementation of coordinated actions with a specific purpose. In the animal kingdom, the objective is basically twofold: individual survival, and ensuring the survival of the species. Of course, it differs whether we're looking at mammals, reptiles, herbivores or beasts of prey. From cheetah to jackal to vulture, witness their deadly hunting techniques and survival skills.Este vídeo está indisponível no momento.T1 EP.2 – The Power of Wings
16 de julho de 200452 minMore than 9,000 types of birds have been identified on earth. They are often very different in size, shape, and color, but all have developed the same evolutionary strategy: 160 million years ago, the front limbs of these reptile descendants transformed into wings, and the avian creatures took to the skies.Este vídeo está indisponível no momento.T1 EP.3 – The Hoof and the Horn
23 de julho de 200452 minGazelles, buffalo, and all antelopes belong to the family bovidae. This large classification includes more than 70 species, most living in Africa.

Dwarf antelopes no bigger than a hare, while the elan weighs more than a ton.Este vídeo está indisponível no momento.T1 EP.4 – The Ground or the Tree
30 de julho de 200452 minThe history of primates began 65 million years ago, when the ancestors of the apes were the contemporaries of the last dinosaurs. Today, on the island of Madagascar, we can find one of the first links in the evolutionary strategy that led to Man. Primates have remained at an elementary stage of development, which gives us an idea of what the primitive species may have been.Este vídeo está indisponível no momento.T1 EP.5 – The Big Ones
6 de agosto de 200451 minOver 10,000 years ago, many animals were considered "mega-fauna". This group consisted of herbivores that had taken a different path than horses or gazelles. Instead of evolving to a lighter, faster animal to escape predators, they decided to grow and to develop thick skins and huge, massive frames. Today, there are a still few animals that, in a way, are relics of this trend.Este vídeo está indisponível no momento.T1 EP.6 – First Years
13 de agosto de 200452 minSize is a very relative notion in nature. You can be the baby in a family of giants or the giant in a family whose largest members measure only a few inches. You can be a little herbivore or a little predator, but all species have one thing in common: helping their young grow to adulthood and independence at the pace corresponding to the species. Sometimes, days behind can mean death.Este vídeo está indisponível no momento.
